I like Ktorrent but I am looking for something that has a client off feature when done downloading. Ktorrent has a shutdown feature but I don't want to shut down my computer after a torrent is done, just the client (also I discovered if Ktorrent shuts down my computer I get a bug report screen when I boot back up). Any suggestions?

I also use Transmission, but I like to seed for a while after download. I keep the defaults of x2, but I often quit before the upload had finished.

If you want to quit when finished downloading then there is an option to call a script when a download is completed. You could shutdown Transmission using this. But please think if this is what you want to do. Why not set it up so that you at least upload the same volume you download (x1)?

I'm not sure I understand what you mean by a client off feature. I run Mint 13 KDE. I installed Transmission because that was the first torrent program I used as a new Linux user just a few months ago. It's simple and does what I need. I can close Transmission without shutting down the entire computer. If I only have one active torrent, for example, I can hilite that torrent and click pause at any time. Transmission is still open but up and down activity is 0. I can resume at any time by unpausing. I tend to seed torrents for quite some time after my download is complete and 15x is not uncommon. When I don't want Transmission running any longer, I just pause all active torrents and close the program. My computer lives on.

Maybe you are looking for an automatic client close feature that activates when a download completes? Don't know, haven't tried.

Like heavy metal said, Qbittorrent is an Utorrent alternative and works on linux, mac and windows.It handle magnet links just like utorrent, where you even can decide where to save the download.

I use kTorrent but I don't need an automatic switch-off setting. I leave the program run as long as the computer is one to upload as much as possible/needed.It does what it needs to do and how it looks is not important either, I never see the window.

No more Windows and Gates since Ubuntu 8.04, used 9.04, 10.04, then switched to Kubuntu because of Unity and Gnome 3.After that it is Mint, used 9 till 17 all in KDE version and loving it.
